RESPONSE OF TOMATO AND CORN PLANTS TO INCREASING Cd LEVELS IN NUTRIENT CULTURE *NESRIN YILDIZ
Abstract:
The aim of this study was to determine the effect of increasing Cd levels
(0, 0.05, 0.1, 1, 2,5,10 and 20 µg mL-1 Cd) on plant dry matter,
mineral content and plant tolerance of tomato and corn grown in nutrient
culture. Tomato and corn seedlings were transferred to the nutrient
solution and Cd was added. Growth differences were evaluated after 3
weeks of Cd applications. Growth sharply increased in tomato but more
gradually in maize. Growth in tomato declined faster than in corn. Statistical
analysis of data showed that there was a significant relationship between
dry matter decrease and mineral content of tomato and corn.
